Membranes & barriers
Description
Intello Rockfol is a polyethylene membrane whose role is to provide air tightness on the internal side of converted loft spaces. Its weight of 85 g/m² gives it good mechanical strength during installation and high durability over time. Its distinctive feature is its hygrovariability factor greater than 100: the permeance of the membrane changes with the ambient humidity, which allows the wall to dry inwards in the event of accidental moisture and protects the roof structure against damage and mould. The product is supplied in 50 m rolls, 1.5 m wide. The overlaps are sealed with the Rockfol KB1 adhesive tape from the same range, whose installation determines the continuity of the resulting barrier.
